Question

Which of the following sets would have a graph with an open circle on 5 and a ray pointing left on the number line?

{x | x E R, x ≤ 5}
{x | x E R, x > 5}
{x | x E R, x < 5}

Answer 1

An open circle on a number means that the number is not part of the solution.
An open circle on 5 means the 5 itself is not part of the solution.
The ray pointing left means that all numbers less than 5 are part of the solution.
Now look at the 3 choices. Which one means all numbers less than 5, but not 5 itself?
